Pulling the Perfect Espresso Shot

Breaking down the layers with a Starbucks barista

There’s nothing quite like a rich shot of espresso. It forms the base of many of the most popular drinks, from the Caffè Latte to the Cappuccino. Watch as Starbucks coffee master Lincoln explains what gives espresso its famous flavor.

Espresso is made by forcing hot water through finely ground coffee under pressure. Any type of coffee bean can be used. As the machine extracts the coffee, three distinct layers form, each with unique flavor notes.

At the bottom of the shot is the layer known as the heart, which highlights a touch of the acidity of the coffee. The middle layer is the body, which brings out its sweetness. The top layer is called the crema, which adds to the aroma, while giving the shot a touch of bitterness to offset the other flavors.
